The productivity of a product is important for every company. There are 5 injection molds with the highest available production hours in April – July. OEE approach are used to measure productivity of the injection mold. Mold SLDX has lowest OEE values, with an average value of 76.6% . Based on measurement OEE, performance rate has lowest rate, with 81.8% rather than other approaches. Performance rate of injection molding affected by cavity efficiency and cycle time performance. Cavity efficiency become root cause that decrease performance rate of mold SLDX, with average cavity efficiency is 84.13% from April- July. Based on 5 whys, wrong sequence on the mold become root cause of problem that cause low cavity efficiency.. Improvement is done by modify sequence of the mold and add detent puller as safety system of the mold to prevent wrong sequence of the mold. There are increasing values of cavity efficiency after modification of mold design from 84.13% to 99.23% from August – September. Increasing cavity efficiency also increase performance rate of mold SLDX from 81,8% to 98.2% from August- September. Increasing performance rate also increase OEE value of mold SLDX from 76.6% to 94.33% from August- September.

Sari

PT. XYZ merupakan perusahaan yang berlokasi di Cikarang bergerak di bidang manufacturing yang memproduksi core. Berdasarkan studi pendahuluan yang telah dilakukan didapatkan data kecelakaan kerja di perusahaan tersebut. Jumlah kecelakaan kerja dari tahun 2016 – 2018 semakin meningkat. Jumlah kasus kecelakaan yang terjadi di tahun 2016 terdapat 10 kasus, tahun 2017 terdapat 18 kasus dan tahun 2018 terdapat 33 kasus. Berdasarkan uraian di atas maka peneliti tertarik untuk melakukan penelitian tentang “Analisa Tingkat Pengetahuan Karyawan Terhadap Penerapan Keselamatan Dan Kesehatan Kerja”. Spesifikasi dalam penelitian ini adalah deskriptif analisis, yaitu penelitian yang mendeskripsikan secara terperinci fenomena sosial yang menjadi pokok permasalahan. Suatu penelitian deskriptif dimaksudkan untuk memberikan data yang seteliti mungkin tentang tingkat pengetahuan karyawan tentang penerapan Keselamatan dan Kesehatan Kerja di PT. XYZ. Penelitian ini menggunakan pendekatan yang bersifat yuridis normatif, yaitu dengan mengkaji atau menganalisa data sekunder yang berupa bahan-bahan hukum terutama bahan hukum primer dan bahan hukum sekunder dengan memahami hukum sebagai seperangkat peraturan atau norma-norma positif di dalam sistem perundang-undangan yang mengatur mengenai kehidupan manusia dan didukung dengan kenyataan di lapangan. Berdasarkan hasil penelitian di dapatkan bahwa tingkat pengetahuan karyawan masih rendah terhadap penerapan manajemen K3 dapat mencegah dan mengurangi kecelakaan kerja, penerapan manajemen K3 dapat mencegah dan mengurangi penyakit akibat kerja, kelengkapan isi kotak P3K di perusahaan, efek bahan kimia berbahaya di tempat kerja, Pemisahan limbah B3 dengan non B3, Arti dalam setiap rambu-rambu K3 (safety sign), Pemasangan Poster-Poster K3 dan Rambu-Rambu K3 (safety sign) di area kerja,

PENGARUH BEBAN KERJA MENTAL DAN FISIK TERHADAP PERILAKU KESELAMATAN PADA KARYAWAN YANG BEKERJA DI KONSTRUKSI

Program keselamatan dan kesehatan kerja sangat penting bagi industri konstruksi karena industri tersebut mempunyai kondisi kerja yang berisiko tinggi menimbulkan kecelakaan kerja. Di Yogyakarta, keselamatan kerja di bidang konstruksi bangunan tidak terpantau sementara para pekerja mendapat upah kecil dengan jam kerja yang panjang menimbulkan beban kerja yang tinggi bagi pekerja. Kecelakaan di konstruksi disebabkan oleh perilaku keselamatan. Beban kerja mental dan beban kerja fisik diduga menjadi faktor yang mempengaruhi perilaku keselamatan tersebut. Penelitian ini bertujuan untuk menguji hubungan antara beban kerja mental dan beban kerja fisik dengan perilaku keselamatan karyawan yang bekerja di proyek konstruksi. Penelitian ini dilakukan dengan melibatkan 130 orang. Metode pengambilan sampel dilakukan dengan metode purposive sampling. Penelitian dilakukan dengan survei menggunakan kuesioner. Kuesioner dikembangkan sebagai instrumen penelitian yang diadopsi dari beberapa penelitian terdahulu. Kuesioner telah diterjemahkan dengan metode back translation dan diuji melalui pilot study sebelum disebarkan kepada responden. Variabel bebas dalam penelitian ini berupa umur, persepsi keselamatan dan kondisi lingkungan kerja. Variabel terikat dalam penelitian ini adalah perilaku keselamatan dan variabel mediasi dalam penelitian ini adalah beban kerja mental. Variabel perancu dalam penelitian ini adalah beban kerja fisik. Data yang diperoleh dianalisis dengan menggunakan SEM PLS. Hasil menunjukkan bahwa beban kerja mental tidak berpengaruh signifikan terhadap perilaku keselamatan karyawan konstruksi. Beban kerja fisik berpengaruh signifikan dan negatif terhadap perilaku keselamatan karyawan konstruksi. Semakin besar beban kerja fisik yang dimiliki karyawan maka membuat perilaku keselamatan karyawan menajdi semakin rendah. Persepsi keselamatan dapat berpengaruh signifikan dan positif terhadap perilaku keselamatan karyawan konstruksi. Semakin besar persepsi keselamatan yang dimiliki karyawan maka membuat karyawan memiliki perilaku keselamatan yang semakin besar. Umur dan kondisi lingkungan tidak berpengaruh signifikan terhadap perilaku keselamatan karyawan konstruksi. Umur, persepsi keselamatan dan kondisi lingkungan tidak berpengaruh signifikan terhadap beban kerja fisik. Beban kerja mental tidak memediasi hubungan antara umur dengan perilaku keselamatan karyawan konstruksi. Beban kerja mental tidak memediasi hubungan antara persepsi keselamatan dengan perilaku keselamatan karyawan konstruksi. Beban kerja mental tidak memediasi hubungan antara kondisi lingkungan dengan perilaku keselamatan karyawan konstruksi. Maka dapat disimpulkan bahwa karyawan konstruksi bangunan tidak dipengaruhi oleh beban kerja mental tetapi dipengaruhi oleh beban kerja fisik. Kata kunci: Beban kerja mental, beban kerja fisik, konstruksi, perilaku keselamatan
